Change location_t to be a 64-bit integer instead of a 32-bit integer in libcpp. Also included in this change are the two other patches in the original series which depended on this one; I am committing them all at once in case it needs to be reverted later: -Support for 64-bit location_t: gimple parts The size of struct gimple increased by 8 bytes with the change in size of location_t from 32- to 64-bit; adjust the WORD markings in the comments accordingly. It seems that most of the WORD markings were off by one already, probably not having been updated after a previous reduction in the size of a gimple, so they have become retroactively correct again, and only a couple needed adjustment actually. Also add a comment that there is now 32 bits of unused padding available in struct gimple for 64-bit hosts. -Support for 64-bit location_t: Remove -flarge-source-files The option -flarge-source-files became unnecessary with 64-bit location_t and harms performance compared to the new default setting, so silently ignore it. libcpp/ChangeLog: * include/cpplib.h (struct cpp_token): Adjust comment about the struct size. * include/line-map.h (location_t): Change typedef from 32-bit to 64-bit integer. (LINE_MAP_MAX_COLUMN_NUMBER): Increase size to be appropriate for 64-bit location_t. (LINE_MAP_MAX_LOCATION_WITH_PACKED_RANGES): Likewise. (LINE_MAP_MAX_LOCATION_WITH_COLS): Likewise. (LINE_MAP_MAX_LOCATION): Likewise. (MAX_LOCATION_T): Likewise. (line_map_suggested_range_bits): Likewise. (struct line_map): Adjust comment about the struct size. (struct line_map_macro): Likewise. (struct line_map_ordinary): Likewise. Rearrange fields to optimize padding. gcc/testsuite/ChangeLog: * g++.dg/diagnostic/pr77949.C: Adapt the test for 64-bit location_t, when the previously expected failure doesn't actually happen. * g++.dg/modules/loc-prune-4.C: Adjust the expected output for the 64-bit location_t case. * gcc.dg/plugin/expensive_selftests_plugin.cc: Don't try to test the maximum supported column number in 64-bit location_t mode. * gcc.dg/plugin/location_overflow_plugin.cc: Adjust the base_location so it can effectively test 64-bit location_t. gcc/ChangeLog: * gimple.h (struct gphi): Update word marking comments to reflect the new size of location_t. (struct gimple): Likewise. Add a comment about padding. * common.opt: Mark -flarge-source-files as Ignored. * common.opt.urls: Regenerate. * doc/invoke.texi: Remove -flarge-source-files. * toplev.cc (process_options): Remove support for -flarge-source-files. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
